REMINDER: Avoid Case Closure Problems; Use Latest Version of Closure Form

The Remediation and Redevelopment Program asks consultants to use the most recent version of the Case Closure Request Form (4400-202), updated in August 2016, which can be found on the Program’s Environmental Professionals web page. Use of this form to request case closure is required by Wis. Admin. Code § NR 726.09(1)

Accessing the form via the link on the web page ensures that you are using the most up-to-date version, which in turn assists with meeting the requirements for an “administratively complete” submittal.

This is a reminder that the Remediation and Redevelopment Program will cease using P.O. Box 8044 for PECFA submittals on June 30, 2018, and will consolidate all incoming mail into our current program-wide mailbox:

Wisconsin DNR – RR/5
P.O. Box 7921
Madison, WI 53707-7921

Please use this mailing address for all PECFA claim submittals. The address has been updated on all forms.

Updated Off-Site Liability Exemption Publication Now Available

The RR Program recently updated a fact sheet on the state’s off-site environmental liability exemptions, When Contamination Crosses a Property Line: The Off-Site Environmental Liability Exemption – Wis. Stat. §§ 292.12 and 292.13, Rights and Responsibilities of Off-site, Affected Property Owners, RR-589 Please recycle old versions of this DNR document and reference to the updated document moving forward.

The update also includes content from and  replaces, a publication titled, What Homeowners, Lenders and Realtors should know about Off-site Contamination, RR-927. More information about the off-site exemption, and RR Program contacts, are available on the DNR’s  web page, Off-site contamination – contamination that crosses property lines.

Demolitions Done Right

Redeveloping old commercial and industrial properties often involves the demolition of buildings and other structures. In addition to carefully evaluating potential asbestos abatement and demolition contractors, the DNR recommends reviewing the agency’s “demolition, construction and renovation” web page to access important information about statutory and regulatory requirements related to demolition activities. Asbestos, lead, mercury and PCBs are top concerns.

Two key publications include, WA-651: Planning your demolition or renovation project, and AM-366: What you need to know about renovation and demolition.

Completion and submittal of Form 4500-113: Notification for Demolition and/or Renovation is always required, at least 10 days prior to the demolition work.

RR Program Hydrogeologist Helps Lead National HRSC Webinar

Already a national leader in cleanup and redevelopment projects, the Wisconsin DNR’s RR Program is about to gain some additional national attention when hydrogeologist David Swimm co-presents a webinar in February with the US EPA’s Office of Underground Storage Tanks (OUST).

The webinar will present various case studies which demonstrate how to apply high resolution site characterization (HRSC) strategies using direct sensing geophysical tools deployed through direct push technologies (DPT) and interpretive techniques to support and improve remediation decisions at sites.

David will present this HRSC webinar along with Tom Kady, and environmental engineer with the US EPA’s Environmental Response Team. Swimm holds BS and MS degrees in Geology from the UW–Madison and West Virginia University, respectively. His graduate work at WVU emphasized geophysical detection of shale gas reservoirs and seismic signal analysis. Following 12 years working in the oil and gas industry, David spent the last 23 years working as a professional hydrogeologist in Wisconsin; first, for private consulting firms specializing in landfill and industrial waste investigations and clean-ups, and later for several state agencies.

Swimm currently works for the DNR’s Policy and Technical Resource Section with the RR Program, specifically addressing detailed NAPL delineation and remedy selection.

This online training is part of OUST’s broader effort to provide technical assistance and ensure that states and tribes are successful as they continue to clean up leaking underground storage tank (LUST) sites.

The webinar will be held on Tuesday, February 20, from 1:00 – 3:30 p.m. CST. Registration is currently open and is accessible at https://clu-in.org/conf/tio/HRSC/.

The webinar will be archived on the Clean-Up Information (CLU-IN) website.

Any questions about the webinar can be directed to Queenie Mungin-Davis at the US EPA (mungin-davis.queenie@epa.gov or 202-564-0685).

US EPA Can Help Remove Contaminants at Abandoned Properties

The US EPA can help your community take care of abandoned or otherwise derelict properties that contain drums, barrels and other containers filled with hazardous substances. EPA staff will evaluate the site, analyze the chemicals and search for anyone involved in abandoning or disposing of the hazardous materials on the property.

If a responsible party is located, EPA will work with them to remove and clean up the hazardous materials. If no responsible party is found or the party is unable to complete the work, EPA may directly perform actions needed to address imminent threats. EPA seeks cost recovery from responsible parties whenever appropriate.

At smaller sites, municipalities can conduct the response action themselves and recover costs from EPA through the Local Governments Reimbursement Program. Reimbursement can include such costs as materials and supplies, renting or leasing equipment, special technical and laboratory services, evacuation services, decontamination of equipment, overtime pay for employees, and replacement of equipment that is lost or destroyed.

Contact John Sager, Federal Removals Coordinator at DNR, to see if a property in your community may be eligible for EPA assistance. His phone number is (715) 392-7822, and his email address is John.Sager@wisconsin.gov.

Updated Vapor Intrusion Guidance Now Available

Following two years of effort and collaboration with external partners to update guidance on response actions for vapor intrusion, the Remediation and Redevelopment Program is pleased to announce that the document, Addressing Vapor Intrusion at Remediation and Redevelopment Sites in Wisconsin (PUB-RR-800), is available to the public. (To see the DNR’s responses to comments received during the public comment period for the draft, please visit click this link.)

Page one of updated publication

Addressing Vapor Intrusion at Remediation and Redevelopment Sites in Wisconsin, DNR publication RR-800

The guidance relates to the assessment, remediation and mitigation of the vapor intrusion pathway at contaminated sites in Wisconsin, for both chlorinated and petroleum substances.

Among numerous updates, the new guidance incorporates the changes made to the Wisconsin Administrative Code ch. NR 700 in 2013. It also includes information found in the EPA’s 2015 vapor intrusion guidance documents, and it provides additional details on mitigation, including principles found in the American Association of Radon Scientists and Technologists (AARST) 2017 national standard on vapor mitigation, SCM-SF-2017).

The RR-800 guidance was most recently updated in 2010.

Questions or comments about the new guidance can be addressed to Alyssa Sellwood.

Soil RCL Calculator Updates

The Wisconsin DNR’s Remediation and Redevelopment Program has updated the numerical soil standards in its spreadsheet of residual contaminant levels (RCLs). The RCLs were determined using the recently-updated U.S. EPA regional screening level (RSL) web-calculator.

A summary of the changes to the direct-contact RCLs can be found in the new document, titled “RR Program’s Soil RCL Spreadsheet Update,” publication number DNR-RR-052f.

For more information and to access the RCL spreadsheet (macro and non-macro versions), visit the Resources for Environmental Professionals webpage and click on the “Soil RCLs” tab.

PFAS Fact Sheets from ITRC

Per- and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants known to impact groundwater and surface water. The information surrounding toxicity, laboratory methods, investigations, and remediation strategies is evolving, and the Interstate Technology and Regulatory Council (ITRC) recently published three technical factsheets summarizing current information on PFAS.  The fact sheets are available online.

These fact sheets specifically relate to:
1. History and Use
2. Regulations, Guidance, and Advisories
3. Naming Conventions and Physical and Chemical Properties

Later this month, ITRC plans to finalize three additional guidance documents on Fate and Transport, Site Characterization, and Remediation, which will be made available on the ITRC website.
